Flexibility (anatomy) For other uses of the term, see flexibility (disambiguation). Flexibility or limberness refers to the absolute range of movement in a joint or series of joints, and length in muscles that cross the joints to induce a bending movement or motion. Flexibility varies between individuals, particularly in terms of differences in muscle length of multi-joint muscles.
This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures. The formula to find the speed of sound in air is as follows: v = 331m/s + 0.6m/s/C * T. v is the speed of sound and T is the temperature of the air.One thing to keep in mind is that this formula finds the average speed of sound for any given temperature.The speed of sound is also affected by other factors such as humidity and air pressure. = 331m/s + 0.6m/s/C * T. v is the speed of sound and T is the temperature of the air.

The propagation of an acoustic wave through a solid polymer can be characterised by two parameters: sound velocity and sound absorption. Sound speed, u (in m/s) is the rate at which sound waves travel through the medium. Sound absorption or attenuation Î± (in dB/m) is a measure of the loss of energy of the sound wave as it travels through the medium: the energy of the sound wave is converted into thermal motions or heat, but usually with a negligible rise of temperature only.
